Hi,

I currently have a home network set up with a Dynalink RTA1320 modem router.  I'm wanting to add wireless access to the network.  I was looking for wireless access points and found them to be a bit scare and expensive, but then I read that I can use a wireless router as an access point.  This would be preferable to me as it has the advantage of having 4 ethernet ports included which would be useful.

So my first question is whether than info is correct.  Can I add a wireless router to my network and use it to add wireless access?

Assuming I can I would be interested in any recommendations for good routers.  I'm looking at the cheaper end of the market.  The main ones I've been looking at are:

Linksys WRT120
ASUS RT-N10
TP-LINK TL-WR740N
Netgear WNR1000

Can anyone recommend one of these, or another in the same price range (up to $100)?  Is there any reason to avoid models with internal antennas or are they just as good as external antennas?

Thanks for your help
Andrew
